Generation of cations from alkoxides: Allylation of propargyl alcohols
Kabalka, George W.,Yao, Min-Liang,Borella, Scott
, p. 11320 - 11321 (2006)
The reaction of alkoxides with boron trichloride results in the generation of cations in the absence of Bronsted acids. The absence of a Bronsted acid can make a difference in subsequent transformations such as allylation reactions. Copyright
Gold(III)-catalyzed direct nucleophilic substitution of propargylic alcohols
Georgy, Marie,Boucard, Valérie,Debleds, Olivier,Zotto, Christophe Dal,Campagne, Jean-Marc
experimental part, p. 1758 - 1766 (2009/06/28)
Gold-catalyzed nucleophilic substitution of propargylic alcohols with various nucleophiles (allylsilane, electron-rich aromatics, alcohols, thiols, hydrides, 1,3-dicarbonyl derivatives, sulfonamides) is described under very mild conditions (room temperatu
Copper(II)-catalyzed allylation of propargylic and allylic alcohols by allylsilanes: a facile synthesis of 1,5-enynes
Yadav,Subba Reddy,Srinivasa Rao,Raghavendra Rao
, p. 614 - 618 (2008/09/16)
Propargylic alcohols undergo smooth deoxygenative allylation with allylsilanes in the presence of a solution of 10 mol % of copper(II) tetrafluoroborate in acetonitrile to afford the corresponding 1,5-enynes in good to high yields under mild and neutral c
Boron trihalide mediated substitution of hydroxyl groups with alkenyl, alkynyl, and allyl moieties
Kabalka, George,Borella, Scott,Yao, Min-Liang
, p. 325 - 329 (2008/12/21)
The coupling of alcohols with alkenyl- and alkynylboron dihalides with high olefin stereoselectivity is described. The reaction provides a facile route to internal acetylenes. Notably, the allylation of propargylic alcohols mediated by boron trichloride p
Synthesis of 1,5-enynes by Broonsted acid catalyzed substitution of propargylic alcohols and one-pot synthesis of bicyclo[3.1.0]hexenes
Sanz, Roberto,Martinez, Alberto,Miguel, Delia,Alvarez-Gutierrez, Julia M.,Rodriguez, Felix
, p. 3252 - 3256 (2008/09/16)
A practical air and moisture tolerant procedure for the preparation of 1,5-enynes from propargylic alcohols by the Bronsted acid catalyzed direct propargylic substitution of the hydroxy group with allylsilanes is described. Also, a straightforward sequent
